It has been reported that in patients undergoing posterolateral lumbar fusion (PLF), the fusion status is not related to the short-term operative results. To determine whether the fusion status influences the long-term operative results of PLF, we retrospectively examined the surgical outcomes of uninstrumented PLF for a minimum of 8 ...

In this prospective study, our aim was to compare the clinical outcome of posterior lumbar interbody fusion (PLIF) and posterolateral fusion (PLF) in spondylolisthesis. A total of 138 patients with spondylolisthesis were randomly assigned to two groups: those operated on with pedicle screw fixation and posterior lumbar interbody fusion by ...

OBJECT: The goal in this study was to demonstrate the safety and efficacy of anterior cervical discectomy and fusion ([ACDF]; single- or multilevel procedure) performed using titanium plates and polyetheretherketone (PEEK) spacers filled with recombinant human bone morphogenetic protein-2 (rhBMP-2) impregnated in a type I collagen sponge to achieve fusion. ...

The literature on four-level ACDF is scanty, and the reported series are not enterely comparable ...

Retrospective study. To more accurately determine the incidence and clarify risk factors. Superior mesenteric artery syndrome is one of the possible complications following correctional operation for scoliosis. However, when preliminary symptoms are vague, the diagnosis of superior mesenteric artery syndrome may be easily missed. We conducted a retrospective study using ...

Radiological analysis. To investigate sacralization of L5 on radiological studies of degenerative spondylolisthesis at L4-L5. Degenerative spondylolisthesis commonly develops at L4-L5. Sacralization of L5 is thought to cause stress concentration at this level, which accentuates degenerative changes and promotes development of degenerative spondylolisthesis. However, there has been no study dedicated ...

OBJECTIVE: The present study was carried out to compare clinical results of spinal fusion in degenerative disease of lumbar between using pedicular screw instrumentation in every pedicle and partial placing the screws in some vertebra to provide immediate stabilization of the spine.

OBJECT: Despite modern stabilization techniques and the use of autologous cancellous bone, bone consolidation does not occur in 10-15% of spinal fusion operations. There is also considerable donor site morbidity. Therefore, there is a definite need for material that has a larger measure of osteoinductivity, osteoconductivity, and osteogenic potential. METHODS: ...

BACKGROUND: The aim of surgical treatment for adolescent idiopathic scoliosis is primarily to prevent progression and secondarily to correct the deformity, whereas the goal of surgical treatment of pediatric spondylolisthesis is mainly to relieve pain and, in patients with a high-grade slip, to prevent progression. The aim of this study ...
